Does pcie 5.0 and pcie 4.0 connectors which goes to motherboard have visual difference?

Does pcie 5.0 and pcie 4.0 connectors which goes to motherboard have visual difference?

So I have noticed that all PCIE 5.0 gen cards what I have, have different looking pins at the connector.

For example this pcie 5.0 gen card has these small "T" shaped connectors:

And this PCIE 4.0 riser card does not have them, only straight golden pins.

So my question is, what is this difference? Does it define which is pcie 5.0 and which is pcie 4.0 ? Or CAN a straight pin connector also work as 5.0 speeds?

Why I ask this, I wan to find out are some PCIE 5.0 adapters just advertised as 5.0 but actually 4.0 because they do not have those upside down T shaped golden pins.
